XB24 After updating with API firmware unable to detect in X-CTU

Had 2 modules, but both are not working, tried manual connection by selecting com port and checking programmable mode too. unsuccessful…

if the firmware not updated successful the problem may happen

try recovery mode to recover the module and check it

Found solution:

Yeah, I recovered the modules. and another complication was i was connecting to my zigbee through my arduino. And those arduino boards are trying to communicate through serial. and this made a clash of data, which was responsible for the improper loading of the firmware.
